This was starting to gain momentum in another thread, so rather than hijack that thread, I decided to start a new one. Quote:
SPP that penny is pretty rare, wonder how many exist. I see it was struck in 1996 the first year of the toonie. Way cool. Quote:
If you have a toonie core struck as a penny I think the only possible date would be 1996, unless they begin striking toonies in 1995, or they continue striking 1995 pennies in 1996.

Since you own some of these, can you still see the grooved edge of the core. That is a cool error. Sorry for getting off topic in that other thread.

Nope. The grooved edge is only on the German planchet cores, which were prefabricated prior to being sent to the RCM production plant in Winnipeg. If fact, it is the opposite, they tend to bulge outwards, where it did not come in contact with the collar die. Here is a photo from a friend of mine, who published on the 1996 German vs Canadian planchets in 2013 (CN Journal, October 2013). Canadian core on the left, disassembled German planchet core on the right.

As I said earlier , I found a toonie core in a roll of pennies and the edge looks like the one on the right, with a groove. Does this mean I have found a German core?

Now I feel like sawing through a toonie just to take the core out.
I don't see the "locking mechanism" on the Canadian one. How does it stay in place?

Think the opposite... the groove is in the nickel ring, the force of the dies striking the coin forces the core metal into the groove.

So that's the difference between a German and Canadian planchet. Is there any way to tell without dismantling it?

Yes... there is. Send me a PM and I'll forward it to the author of the October 2013 CN Journal article. He should be able to send you a PDF of that article.

I think I can find the October 2013 CN journal in my library. I'll check it out when it opens on the 5th.

I knew about yours Smallcentguy, but have not seen it in hand... I think at one of these future Coin Expos, you need to come out after the show, and sit with us in the pub for some show-and-tell.. I really have not seen much of your stuff...
